Problem while displaying iViews in Portal Page

Hello all,

I am working on PDK.NET and i have created two iViews. One iView contains combo box and label control and other iView contains Tab strip control.

When i have added these two iViews into the SAP Enterprise Portal page, it behaves strangely.

The problem is in page layout, When I add the iView containing combo box under the iView containing the Tab strip control it works fine but when I reverse the position of the two, controls inside the tab strip control are not getting displayed.

Does anybody knows the reason behind this? what is the possible solutions for the same?

Thanks in advance,

Prashant
